Engine codes and car is misfiring

[Tarponboy95]

Has anyone experienced these codes before? I was driving last night with cruise control on and I felt the engine loose power and the engine light and TCS light cans on. The car has a severe misfire and bad vibration cause by the misfire on acceleration. It’s down on a lot of power and barely gets up to 60mph. I took it to the dealership and they haven’t told me anything yet.

Did you ever figure out what was wrong? I can think of two issues.

1. You are using the code scan function which pulls all sorts or random past and not tested codes. Run the scan with each individual system. I have an ethos edge and this really narrows down to what is wrong.

2. Check your spark plug gaps. Specifically #4 plug. My sonic was stumbling at acceleration, and I would get less power throughout all speeds. I would also get the occasional misfire. Replaced NGK iridiums with AC Delco Iridiums and set gap to .028 and replaced coil pack(Mine has 125k miles, but has been doing this for about 15k miles).

Problem solved on mine.
